Eficacia de la auscultación cervical digital con fonendoscopio y sonar doppler para el análisis acústico de la deglución en pacientes con difagia.

Abstract

INTRODUCTION: to analyze the efficacy of digital cervical auscultation as support for the clinical evaluation of dysphagia through acoustic swallowing. METHODS: Systematic review with bibliometric analysis that allows obtaining information on the ongoing research process, in addition to the scientific effectiveness and impact of sources. RESULTS: the initial search obtaining 1,392 articles, of which the highest number was found in the Springer Link databases with 48%, Elsevier with 46% and the lowest number of articles related to the subject were found in the Pubmed databases. 5% and Scielo 1%. Once the first filter was applied, selection from the title, summary and elimination of duplicate articles, it was possible to obtain a total of 26 articles. ANALYSIS AND DISCUSSION: According to the studies reviewed in this investigation, digital cervical auscultation with a stethoscope and Doppler sonar are Accepted instruments and considered useful for the clinical evaluation of dysphagia, the authors refer to digital cervical auscultation as a tool that provides spectrographic evidence. CONCLUSIONS: In the studies reviewed, no differences were found between the levels of sensitivity and specificity of the studied methods, demonstrating their importance and efficacy in supporting the clinical evaluation of dysphagia.
